Description

DETAILED DESCRIPTION OF THE INVENTION

<Technical Field> The present invention is a sunshade for a vehicle, and an object of the present invention is to protect the inside of a vehicle including an instrument on a dashboard from overheating due to sunlight while parking.

[0002] Sunshades similar to shutters on windshields are well known. The shutter is operated by a special lever, which covers the windshield when the car is parked,
When the car starts, it is removed from the windshield (DE, B2, 34139)
66).

However, this device has a rather complicated design. In addition, the shutter is in a vertical position, but the windshield is somewhat inclined. Thus, this blind does not protect part of the instrument panel from the sun.

[0004] Other devices for protecting a vehicle from the sun's rays include blinds fixed to the frame of a vehicle window opening. The blinds are hingedly fixed to one another and are kinematically connected to the driver's seat (SU, A1, 1606358).

[0005] These devices utilize several complex technical solutions and, more importantly, are not very reliable because hinged joints or rotary blinds can become immobile. The construction of this device is fixed and requires a considerable amount of time and specialized tools to install and remove it. At the same time, the constant use of this device is extremely dangerous as it can lead to a sudden loss of visibility while driving, causing an emergency. This type of device is also single-purpose. For example, it is difficult to display information using this blind.

[0006] Devices exist that protect the interior of the vehicle from the sun's rays, including glossy window panels installed on the cab wall from the outside. The window panel includes two plates made of unhardened quartz glass and an intermediate metal layer composed of a dark corrugated foil that provides protection from sunlight. The glossy window panel is fixed by hinges located at the bottom of the panel (RU, C1, 20228).
17).

[0007] These devices are very complex and expensive. Moreover, said devices considerably limit the field of view and cannot be used to display information.

[0008] There is also a sunshade for a vehicle windshield comprising a seat and a fastener necessary for fixing the device from inside a window. The upper horizontal edge of the seat is coupled to the body of the vehicle, and the lower edge has a circular crossbar with a tapered end. The crossbar is made of an elastic material and its lower end can be moved along a guide installed on the side of the vehicle window so as to be parallel to the glass, but the length of the guide is determined by the upper end and the support. Longer than the distance between, the support has a frictional coating and provides interaction with components inside the vehicle located under the window. The length of the crossbar is longer than the distance between the guides. The device has a fixture that secures the panel in a vertical position.
That is, a maze-like recess (la) opened from the crossbar side, which is located in the guide support and passes through the end of the fixture and the fixture of the folded panel and secures it.
A fixture, manufactured in the form of a byrinth recess, that secures the panel in the open position, is manufactured in the form of a push button located on either side of the top of the panel along the side edge (SU). , A1, 1754493).

This device, like the one described above, is complex from a structural and kinematic point of view and is very expensive due to having many moving parts. In addition, the movement of the components of the device being guided, and in particular the movement of the crossbar, often results in the crossbar bending or stuck. This phenomenon is exacerbated by the fact that vibrations generated by the movement of the vehicle affect the adjustment of the mechanism, the state of the mounting fixture, and the like. This device is virtually fixed because it is rather complicated to assemble and disassemble and requires time, tools and special skills. Although it is possible to use this device when driving a vehicle in any weather conditions, there is some limitation of visibility.
If the panel is used to display advertisements or other information, the panel must be completely spread out, otherwise some of the messages that may contain the most important information will not be visible to potential customers.

[0010] There are optical protection devices for vehicle windshields that include a corrugated panel with a sawtooth cross section. The generatrice is perpendicular to the upper and lower edges of the panel and the mounting of the panel on the inside of the windshield is manufactured as a suction cup with a projection on its back (US, A, 4647102). The rod is permanently attached to the edge of the panel, with the rigid rod on the right and the adjustable rod on the left. The suction cup is connected to the rigid rod by an element slidable along the rod and fastened thereto by screws. The suction cup is located only on the right side. There should be two or more, preferably three or more, suction cups. The left side of the panel is secured by an adjustable rod, which is long enough so that when the adjustable rod is placed between the materials forming the windshield near the windshield, the rod will have a shade. Sufficient stress to open and close is applied. To prevent the panels from sagging, a mechanism with flexible links is used.

However, this device has several disadvantages. First, the device is complex from an engineering point of view. The panel and the suction cup also have two separate rods with different functions, a dedicated member for connecting and adjusting the suction cup to the rod, and a mechanism with a flexible link. In order to remove and attach the device from the windshield, it is necessary to separate and attach the suction cup to the glass, but as is well known, after several installations, the rubber suction cup loses its ability to adsorb to the glass surface. If the driver does not remove the device while driving, the device will limit the visibility of the passenger, and more importantly, in the event of vibration, the friction fitting of the clamping rod is not reliable. The left edge of the device can be dislodged, which not only limits the passenger's view but can also cause an accident. Fixing the tightening rod by inserting it between the upper and lower sides of the frame (rubber cord) is reliable because it is very difficult to achieve the required degree of interaction between the rod end and the cord There is no. The rod should be compressed and flexed longitudinally to provide the necessary tension from the rod end to the cord. The length of the tightening rod should correspond to the length of the windshield, and for certain types and dimensions of vehicles, custom made equipment is required. Also, the bending of the rod deforms the panel and turns the left end, which reduces the protective ability of the device. The rubber cord is damaged due to the constant contact with the end of the clamping rod.

DESCRIPTION OF THE INVENTION It is an object of the present invention to effectively protect the interior of the vehicle and the equipment on the instrument panel from the sun's rays while the vehicle is parked, while at the same time advertizing information to a large number of people. The aim is to develop a simple, inexpensive and reliable light protection device for vehicle windshields which also serves as a display. At the same time, the device is inexpensive, simple and reliable in operation, which means that it can be quickly assembled and disassembled without tools, so that even inexperienced persons can assemble and operate this device. Means what should be done. When this device is disassembled, it takes up minimal space.

[0013] These problems are solved in this new invention by a light protection device for a vehicle windscreen having a corrugated panel with a sawtooth cross section having a generatrix perpendicular to the upper and lower edges of the panel. The fastener for fixing the panel to the inner surface is manufactured in the shape of a suction cup having a projection on the back side of the suction cup. An opening is provided in the upper corner of the panel that interacts with a suction cup projection formed in the shape of a hook. The lower edge of the panel is in the operating position, near the windshield on the dashboard,
The panel can contact the surface of the dashboard. At least one of the panels
Information can be displayed on one side.

[0014] The applicant has not found any source of technical solutions similar to the claims. Thus, in applicant's opinion, it can be concluded that the present invention meets the "novelty" (N) criteria.

With the realization of the present invention, new important properties have been achieved. Two (but not more) mountings symmetrically located on the windshield position the panel in an operating position near the windshield on the dashboard, allowing the panel to touch the dashboard surface. Deflecting the panels provides a secure installation of the panels. Two points are enough to fix the panel on the windshield.
The design of the device is very simple and space saving. Due to the fact that the suction cup is not fixed to any part of the device, the device can be easily removed and reinstalled from the windshield, while the suction cup remains on the windscreen, but is very small, limiting visibility Never. Since there is no need to remove and reinstall the suction cup, the life of the suction cup and the reliability of fixing it on the windshield are improved. During operation of the vehicle, the corrugated panel cannot open automatically because the device is removed. Despite its simple design and low cost, the device is very reliable and not only provides effective protection from the sun's rays inside the vehicle containing the equipment, but also informs many potential customers Can be used to display advertising. No tools are required to install and adjust the device, even a screwdriver, and only takes a few seconds to install. When the device is removed, it collapses into a thin, narrow band, requiring minimal storage space. When the panel is installed on the windshield of an automobile or when the panel is opened and shown without being installed on the windshield, the information described on the panel can be shown.

The Applicant has not found any information regarding the effect of particular features of the invention on the final technical result. Thus, it can be concluded that the present invention meets the "Inventive Step" (IS) criteria.

The present invention will now be described in an exemplary detailed description with reference to the accompanying drawings, in which the following items are presented.

BEST MODE FOR CARRYING OUT THE INVENTION A light protection device for a windshield of a vehicle includes a panel 1 and a fixture formed in the shape of a suction cup 2 fixed to an inner surface of a windshield 3. The panel 1 is corrugated in a sawtooth cross section and is formed from a flexible material such as paper, cardboard, plastic or fabric with special impregnation. In this particular example, panel 1 is 0.4 m
It is formed from m-thick cardboard. The corrugated bus is perpendicular to the top and bottom edges of panel 1. The panel 1 can be spread out just to cover the width of the windshield 3. Several dotted lines drawn at the bottom of panel 1 are parallel to its lower edge. The panel can be cut at these lines and reduced in height (not shown). These lines are drawn or embossed. The distance from the cutting line to the upper edge of the panel 1 corresponds to the height of the windshield of various types of motor vehicles. This allows the same awning device to be used on a variety of different vehicles. Also, as shown in this particular example, the lower part of the corrugated panel 1 may be provided with perforations 4 arranged parallel to the lower edge. By cutting off unnecessary parts of the panel 1 along the perforated line 4, it is possible to adapt the light protection device for the windshield of the vehicle to the specific shape of the motor vehicle. A circular opening 5 is provided in the upper corner of the panel 1. The suction cup 2 has a hook-shaped projection 6 at a central portion on the back side. Thereby, the panel 1 can be fixed to the suction cup 2. The area around the opening 5 can be covered or laminated with a polymer film to prevent breakage after prolonged use. In its operating position, the lower horizontal edge of the panel 1 contacts the dashboard 7 near the windshield 3. In this particular embodiment, the advertising information 8 is written on the outer surface of the panel 1 facing the windshield 3 of the motor vehicle. Other information (in this particular example, a map 9 showing a view of the city) is written on the inside surface of the panel.

This device is used as follows. The light protection device is stored folded, for example, in a vehicle door or seat pocket. The suction cup is fixed to the upper corner of the inner surface of the windshield 3. If the sunlight is very strong when parking, the light protection device is removed from the pocket and the panel 1 is widened to a width corresponding to the width of the windshield 3. The hook 6 of the suction cup 2 is inserted into the opening 5 of the panel 1 and the lower horizontal corrugated edge of the panel 1 is installed on the dashboard 7 near the windshield 3, whereby the dash not only on the inner surface of the car but also on the dash. Devices installed on the board 7 can also be protected from overheating.

This device is disassembled as follows. The panel 1 is removed from the hook 6 of the suction cup 2. The removed panel 1 is folded along the corrugated generatrix to obtain a small, thin band-like space-saving shape that takes up virtually no space when stored inside a car. The suction cup 2 together with the hook 6 can be removed from the windshield 3. Since the suction cups are of small size and are located in the upper corners of the windscreen 3 so as not to restrict the field of view, it is also possible to keep them attached to the windscreen.

The information 8 or 9 described on the surface of the windshield 1 is used for driving the vehicle 1 whether the panel 1 is installed on the windshield 3 of the automobile or when the panel 1 is shown without being installed on the automobile. And passengers. The information 8 written on the outer surface of the panel 1 indicates that the panel 1 is installed on the windshield of a car.
